I'm not sure whether this NVMe drive supports queued trim, or if it's
intentionally slow to avoid the pausing problems seen on non-queued
trim drives? I'm offhand not experiencing any hangs while issuing this
trim, including scrubbing this file system while trimming it (seems
ill advised, but I like misery). However I do get a circular lock
warning...
